I have not used it yet, but it will not make it soon as the shipping seems to be at the beginning of the year! ! I was glad if you could do it a little more quickly. Because it is supposed not to be able to cancel, this site may be disgusting · · ·

I was saved because I could purchase a small amount cheaply. Approximately 10% of the number, there is a sag of plating about 5 mm in tip, slightly thicker. There are something that feels stuck when turning the nut with your finger and some that does not turn unless you put in considerable force. However, if you change the nut it may turn smoothly, and if you rotate it with a tool it will not turn unnoticed. I think that there is no problem level for practical use. As a feed screw, the plating bolt has a problem in durability, but it is cheap for creating a prototype and it is saved.
